' HERBERT A.OLIVER ERNEST L. McDONALD BY 1W J ATTORNEYS DISPOSABLE COFFEE CONTAINER BACKGROUND OF THE INVENTION The desirability of a sufficiently economical coffee making package to enable a person to brew clear coffee of the proper strength, without measuring the ground coffee, and without thereafter cleaning loose grounds from the receptacle therefor, as in the conventional percolators or other type coffee makers, is evidenced by the many attempts that have been made to produce an acceptable package.

The central riser or tube of a conventional percolator through which the hot water rises and from which the latter is discharged at its upper open end is employed to support the package of the present invention. This in itself is not new.

Prior devices have not been adjusted along the central stem or riser of a percolator, either due to the provision of a screen or the like extending over the upper open end of the riser, or the employment of a fixed projection or bead along the riser supporting the package at a fixed level. Also, there are instances in which the top of the percolator must be employed to deflect the water ejected from the riserthus changing the efficiency of water distribution with each change in the size of the package, and in most instances of which we are aware, the packages have not been sufficiently economical to make to be disposable.

The present invention overcomes the above objections, and others, as will appear in the drawings and detailed description.

SUMMARY The present invention provides a disposable coffee container in the form of a package complete with coffee adapted to be supported on the upper end of the conventional hollow stem, or water-riser, in a conventional percolator.

The package has top, side, and bottom walls, in which the top wall is imperforate, and .the bottom wall includes a perforate or porous marginal portion and means for removably holding the package at the desired position on the riser independently of any projections on the riser and independently of the conventional receptacle on the riser, and which top and bottom walls are constructed and formed to provide the most efficient distribution of the coffee and of the water ejected from the riser when the percolator is in use.

In the preferred form, the sidewalls and the bottom wall are of paperlike porous material similar to filter paper used in coffee makers, and in all forms of the invention the top and bottom walls are uniformly spaced-apart in each of the different sizes and the upper end of the water-riser is unobstructed to eject hot water, and furthermore, the packages are adapted to be packed closely in hermetically sealed cans and then closed to prevent escape of coffee therefrom.

DETAILED DESCRIPTION In FIG. 1 the body 1 of an ordinary percolator has a top 2, and an upwardly domed base member 3 provides a false bottom having a vertically extending central stem or riser 4 centrally secured at its lower end to said member. The riser is open at its upper end in the upper portion of the body 1 and its lower end opens into the space between the base member 3 and the bottom 5 of the body I. Said base member is loosely supported on bottom 5, and the former may or may not be perforated, but in any design, when the water in the percolator is hot there is ready access of said water to the lower open end of the riser for upward flow of water through the latter for discharge from its upper open end.

Usually riser 4 is formed with an outward projection 6 for supporting a conventional perforated receptacle, at a predetermined fixedlevel within the upper portion of the percolator. This perforated receptacle is designed to hold a sufficient amount of ground coffee for water sufficient for the maximum capacity of the percolator, and the distance between the upper open end of the riser and the upper level of the bed of coffee will vary according to the amount of water. In some instances the riser and receptacle are rigidly secured together.

In the present invention it is immaterial whether the riser has or does not have a projection 6 or the equivalent thereof, or whether a conventional receptacle, such as indicated in dot-dash line 7, is rigid with the riser 4 or is removable therefrom. A receptacle, such as 7, is superfluous.

The present invention comprises a horizontally disposed package, generally designated 8, having an imperforate, preferably circular top wall 9 FIGS. 2, 3) that may be of any suitable rigid or semirigid material, and which top wall is formed with a central portion 10 elevated above its outer peripheral marginal portion 11 (FIG. 2). An annular flange I2 depends from the outer edge of said marginal portion, and convergently upwardly extending,relatively narrow annular walls 13 connect the central portion 10 with the marginal portion 11. The flange 12 may be formed to provide a radially outwardly opening annular recess or groove 14 therearound.

The coffee supporting portion of the package comprises an upwardly opening holder generally designated 17 (FIGS. 1, 2), of porous, sheet material, such as the conventional sheet filter material used for some tea bags and coffee makers, which material is strong and tough, and although it may sag slightly when wet and under the weight of water, as indicated in FIG. 2, it will normally retain its shape prior thereto, as shown in FIG. 1.

Holder 17 has sidewalls 18 that are adapted to receive flange 12 therein for securement of the upper marginal portion of walls 18 to said flange by any suitable means, one being a tie' strand 19 (FIGS. 1, 2). The outwardly opening recess 14 provides for depression of said upper marginal portion of walls 18 into said recess when strand 18 is tightened, and upon tying the strand, a tight seal is effected between the holder 17 and the top wall as well as firmly securing the top wall and holder together as a unit.

Holder 17 may be formed from a planar sheet of porous, fibrous, paperlike material, as hereinbefore mentioned, having a central portion 20 (FIG. 8), providing a bottom for the holder or package, the outline of which is defined by fold lines or creases 21 providing an octagonal arrangement and divergently outwardly extending fold lines 22 at the adjoining ends of the lines 21 for pleats 23 (FIG. 1) to form the sidewalls 18. Other arrangements of fold lines or creases may be employed, provided the holder has sidewalls and a bottom wall as illustrated. The holder may be molded or similarly shaped to generally cup form. In any event, the economy in the use of paperlike porous sheet material, as well as its efficiency, selfsustaining stiffness, and ability to withstand disintegration under the relatively high temperature of boiling water are highly desirable features.

It is also important to note that the central portion 20 of the sheet forming the coffee holder is the bottom wall of the latter, and is formed with cross cuts or slits 24 centrally thereof, or these may be lines of weakness so that the tabs 25 formed between the right angle slits may readily flex upwardly to permit the riser to pass upwardly into the holder when the package is installed on the riser. However, until the riser is forced into the holder by downward movement of the holder onto the riser or vice versa, the holder is closed against any loss of the ground coffee therein, which ground coffee is placed in the holder to a level spaced substantially below the top 9 and the upper open end of the riser, to permit swelling of the ground coffee and efficient distribution of water, a bed of which coffee is designated 26 in FIG. 2.

Inasmuch as the imperforate top wall 9 of the holder should be spaced above the bed of coffee 26 and above the upper open end of the riser 4, a horizontal, circular, supporting disc 27 is provided as a support for the central portion of the holder 8, which disc may be of plastic material. This disc has a plurality of vertical posts 28 (FIGS. 4, 7) secured at their lower ends to said disc, equally spaced from each other and from the central vertical axis of the disc. Said disc 27 is of resilient material, and is formed with a pair of right-angle cuts or slits 29 (FIG. 4) that substantially correspond to slits 24 in the bottom 20 of the holder 17.

The upper ends of posts 28 are each fon'ned with a head 30 and a restricted neck 31 immediately therebelow (FIG. 7). The central portion of the top wall 8 is formed with openings positioned to pass the heads 30 of posts 28 upon the heads being forced through said openings, so that the edges of the openings will snap into the annular recess or neck portion 31 of the posts adjacent to their heads.

In forming the package, the disc 27 is positioned coaxially with top wall 9 with the posts and holes in said top wall respectively in alignment, and after the holder 17 is filled with the desired amount of ground coffee 26 and the top wall 9 and holder 17 are secured together the posts 28 are pushed through the bottom of the holder 17 and heads 29 are pushed through the openings in portion 10 of top wall 9 to secure disc 27 to said top wall but spaced the correct distance from the latter. By this arrangement, the dimension of the central portion of the package, axially thereof, is always the same irrespective of any sagging of the holder outwardly of the outer edge of disc 20.

Disc 27, being resilient, flexible, and semirigid, the tabs 33 at the sides of slits 29 will yieldably grip the riser when the holder is positioned on the riser by forcing the holder and disc 27 downwardly onto the upper end of the riser. Thus the holder will remain stationary during the making of coffee.

Posts 28 and walls 18 of the holder may respectively be of different lengths and vertical widths according to the amount of ground coffee in the holder, where the horizontal dimension or diameter of the holder is the same. Obviously, any of the dimensions may be varied to suit conditions.

A circular adapter plate or disc 34 is provided for use below the supporting disc 27. Said disc 34 may be of the same material as disc 27 and is preferably formed with an upstanding annular bead 35 around its outer periphery on which the marginal portion of disc 27 is adapted to be seated. Disc 34 is centrally formed with an opening the edge of which is defined by a plurality of radially inwardly projecting yieldable locking tabs 36 having convexly rounded riser-engaging edges adapted to be sprung to yieldably engage the riser for holding the package horizontal within the container 1 at whatever level is desired, upon sliding the disc 34 onto the riser.

The adapter disc 34 is initially placed on riser 4 in the desired position for supporting the upper open ends of the riser 4 spaced the most efficient distance above the upper open end of the riser. Thus in larger packages the disc 34 will be lower and post 23 will be longer than for smaller packages. The disc 34 may remain on the riser once adjusted.

Any ground coffee that might escape from the openings formed in the bottom 10 of the holder and through the slits in the disc 27 will be collected on disc 34 inwardly of bead 35.

Preferably a central, downwardly projecting substantially conical deflector 38 is formed on the central portion 10 of the top wall 9 of the package, which deflector will deflect water ejected vertically upwardly from the upper open end of riser 4 when the water in the body 1 is heated and the package is on the riser and in the body of the percolator. The arrows 32 (FIG. 2) generally indicate the manner in which the water is ejected from the upper open end of the riser, and it is to be noted that it is directed onto the main bed 26 of the ground coffee held in the porous holder 17, and by supporting the central portion of the bed 26 elevated by means of disc 27, the bed does not tend to urge the ground coffee inwardly around the riser, but maintains the bed in a position to intercept the main flow of water.

Tabs 33 on the disc 27, being resilient, are self-closing when the package is slipped off the riser 4, with the result that the grounds are retained in the package.

Obviously the conventional perforated receptacle indicated in dot-dash line in FIG. 1 is not necessary nor does it perform any function insofar as the present invention is concerned. Where a projection 6 is used to position the conventional receptacle for the ground coffee, it is normally spaced from the upper end of the riser a distance for supporting the receptacle in a position in which the latter holds the maximum amount of coffee. Where the receptacle, such as indicated at 7 in dot-dash lines (FIG. 3) is removed, the projections 6 will in no way interfere with the positioning of the package 8 on the riser 4, and it is seen that where it may be desirable to brew two or four cups of coffee in a six or eight cup percolator, the upper surface of bed 26 will be at the most efficient position relative to the upper open end of the riser for brewing the coffee, and this level will be the same for a four, six or eight cup package or any other size. The adapter 34 is merely moved to the desired level, and the outside of the riser may be suitably marked to indicate the different levels for different sized packages as at 39 (FIG. 1).

FIG. 9 shows a modified form of the invention, in which the holder 40 is all of semirigid but thin plastic material having perforated bottom portion 43 that is the outer marginal portion having sidewalls 44 integral with the edges of said portion. The central part 45 of the bottom wall may be imperforate and elevated above the level of the marginal portion 43, but it has the same cross cuts centrally therein as shown at 29 in FIG. 4, and the top wall 46 may be identical to wall 9 of FIG. 2.

Said sidewalls 44 are formed along their upper marginal portion 47 to provide a cross-sectional contour that is complementary to that of the flange 48 on top wall 46, so as to snap into holding engagement with flange 9 when said marginal portion 47 is inserted into the flange 48.

The adapter 34 is still desirable when the package of FIG. 9 is used, being initially positioned on the riser 4 to fix the position of the package on said riser, and thereafter the package is forced onto the riser in the same way as the support 27. The bottom wall 45 functions the same as disc support 27, but the posts 28 are not required inasmuch as walls 44 are semirigid.

It is to be understood that the present invention is intended to include any modifications that may come within the scope of the claims appended hereto.
